..and only the keyboard keys are mechanical. The rest of them are membrane. That bothers a -lot- of people. There doesn't seem to be a plethora of choice here in Canada given your request (read: backlighting) other then Razer. I hate hate hate the font they use personally. the g710 (and the Corsair) is the only other option you really have. Did you have a particular switch type in mind?

I don't know about the Corsair K90, but I would stay away from the K60 for gaming If I were you. The keyboard looks great and the build quality is top notch, but for some reason it ghosts a lot. It usually happens when I'm scrolling through pictures or pressing the space bar repeatedly. While ingame, sometimes some of the buttons stop working all together like it gets jammed or something.
